Opel/Vauxhall is to unveil a super sports car concept called Astra Coupe OPC X-Treme at the Geneva Motor Show. The road-going two-seater is based on the Astra Coupe V8 racing car that last season successfully competed in the German Touring Car Masters (DTM).

With a 4.0-litre V8 engine, rear-wheel drive and a sequential, six-speed transaxle gearbox, the engineers at the OPC motor sports department (Opel Performance Centre) have taken over the thoroughbred racing technology of the DTM car for the study. The engine provides the stunning red concept car with 326kW/440PS and maximum torque of 530Nm, taking it to a top speed of over 187 mph.

Among the most eye-catching features of the Astra Coupe OPC X-Treme are its gull-wing doors which, supported by gas-filled struts, swing gently upwards.

The powerful coupe rolls on specially developed 20-inch tyres (245/25 at the front and 285/25 at the rear). Based on the same engineering as the DTM car, the study not only proves its suitability for the road, it also demonstrates the synergies that are possible between motor racing and series production.

The foundation for the Astra Coupe OPC X-Treme and for the DTM racing cars is the Astra Coupe, which was launched last year. The two-door coupe combines elegance and performance with a high level of equipment.

Also making its public debut in Geneva is the new Astra Convertible.
